I've got a Panasonic RA-6600 receiver I'm working on. I think I've identified a blown component but I can identify what it is. I've posted a picture here. The leads are cut off of course. It is marked "IR7K" on the outside. Any help wpuld be greatly appreciated...

It showed some scorching underneath it so I'm going to assume it's bad.

@GopherT...Yes there are actually three others right near it....

Then it is a diode - 4 single diodes to make a bridge rectifier.

You can go and track down some diodes that meet the power requirements or you can buy a single bridge rectifier that can be used in place of the four diodes. They are available at RadioShack. Getting one that is oversized is usually not a problem. You will have two wires coming in from the transformer - connect those to the AC sine wave symbols. Then you will have two wires going to the two big capacitors the two caps are connected to each other and each has one leg connected to the diodes. Look for a stripe on one capacitor with - - - symbols. This goes to the (-) of the bridge rectifier. The last leg of the bridge rectifier connects to the other capacitor.
